SEWING-MACHINE.

useful Improvements in Sewing-Machines,

of which the following is a specification. This invention relates to sewing maclnnes, and more particularly to a machine for sewing shoes and similar purposes.

One of the main objects of the invention is to provide a machine so constructed as to permit threads of different colors to be used selectively so as to facilitate sewing shoes of different colors or shades. A further object is to provide a machine having a rack for supporting a plurality of spools of thread of different colors, a needle bar being provided for receiving these threads, tensioning and take-up devices being mounted intermediate the spool rack and needle bar.

A further object is to provide a needle bar having means for receiving a plurality of threads and also being provided with means for releasably securing the free ends of the threads which are not being used. Further objects will appear from the detailed description.

In the drawings:

Figure 1 is a view in side elevation of a machine constructed in accordance with my invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a fragmentary vertical section through the needle bar.

Fig. 4 is a section taken substantially on line 4-4 ofFig. 3.

Fig. 5 is a detail top plan view of the needle bar and the machine for connecting the same to the take-up lever.

Fig. 6 is a section through the tensioning device.

Fig. 7 is a perspective detail of the takeup arm.

The machine designated generally by A is of standard construction having the upper bar B, head C, lower arm D, and presserfoot E, all as usual. A take-up lever 1 is rockably supported on the upper bar B and is provided,at its forward end, with a take up member or arm 2 which is pivotally secured in a recess in the lever by a pin 3, the inner end of the arm being cut out to provide a stop finger 4:. The arm is normally held in raised position by a leaf-spring 5 secured thereto at its outer end and extend- Specification of Letters latent.

ing into a recess in the lever 1 so as to lift member 2. The finger 4 engages the inner end of the shank 6 of a clevis 7 secured in the forward end of lever 1 so as to positively limit the upward movement of member 2.

The clevis is secured by pin and slot connections to a lug 8 formed integral with the needle bar 9 reciprocable through head C, by means of a pin 10 secured through the arms of. the clevis 7 and passed through a slot 11 in ear 8. By this construction, when the needle bar 9 is reciprocated during the sewing operation, the lever 1 and member 2 will be oscillated in the well-known manner so as to take up any looseness or slack in the thread. For this purpose, member 2 is provided with a head 12 formed integral therewith provided with the three arms 13, 14:, and 15 extending in spaced parallel relation and each provided at its forward end with an integralthread-receiving eye 16, 17, and 18, respectively. This take-up operates in the well-known manner common to machines of this type and need not, therefore, be further described in detail.

Adjacent the inner end of arm B is secured a spool rack 19 provided with the spaced spool posts 20, in this case 3 in number. These posts cooperate with the rack to rotatably support three spools a, b, and c of thread of different colors as black, white, and tan. The threads from these spools are passed forwardly on arm B through suitable eyes provided for this purpose and thence through a tensioning device and the take-up, being then inserted through the needle bar 9. The tensioning device is shown more clearly in Figs. 1 and 6 of the drawings. This device comprises a post 21 secured in head G and provided at its upper end with a knurled flange 22, sheet metal disks 23, 24, 25, and 26 mounted about the post so as to be slidable thereon, and a coil tension spring 27 mounted about the post and confined between the flange 22 and the uppermost disk 26. The spring acts to resiliently force the disks together, and the threads from the spools a, b, and c are passed between the successive pairs of disks so as to be gripped frictionally thereby thus tensioning the thread in the well-known manner. The lower portion of post 21 is threaded, as at 21*, so that the effective v 30 extending the full length thereof,- The bar is further provided, in its lower end portion, with an axial bore 31 for receiving 7 the needle which is secured therein by a set screw 32. In using this machine, but one thread is inserted into the needle at a time, the loose ends of the other two threads be.- drawn up about the lower end of the needle bar 9 and; frictionally secured by being inserted between a spring clip 33 fitting snugly about bar 9' a short distance above the lower end thereof and detachably secured to the bar by a screw 3%, the free endoi this spring being turned out slightly, as at 35 to facilitate insertion of the threads between the same and the bar. By this arrangement, it is possible to quickly and easily change the color of the thread being used to correspond with the color of the shoe or other piece of work being operated upon, without t-he'necessity of completely rethreading the machine. For instance assuming that the spool carries black thread, B white thread, and G tan thread, and the sewing of a black shoe has been "completed and it is desired to sew a tan shoe: in this case, the thread a from spool A which-is passed through here 30 of bar 9 and threaded through the needle 36 will be with drawn from the needle and inserted between the spring33 and bar 9, after which the-tan thread c from spool G which is inserted through bore '28 of the ,bar,,will be released from spri1-ig 33 and inserted through the eye of needle- WVhen this has been done, the machine threaded with tan thread and may be used for sewing the tan shoe. This renders it possible to quickly and easily change from one color of thread to: another so as to. accommodate the color of shoe being operated upon without neces- Sitating the complete rethreading of the ma Chine as is now done, thus effecting a material saving in worl; and time.

It will be evident that there may be slight changes made in the construction and alfliellgementof the details. of my invention without departing from the field and scope Qif he same, and I intend to include all Such variations, as. fall within the scope of th ppe ded claims, inthis application in which a preferred form only of my inveni mli d losed.
